Methods and devices for collection of soft tissue

摘要

A tissue sampling apparatus comprises a tubular body having a primary lumen for receiving a tissue sample. The tubular body includes a distal end, a proximal end, and a longitudinal axis extending from the proximal end to the distal end. The tissue sampling apparatus further comprises a cutting cylinder having a distal cutting edge, which is movable both distally and proximally relative to the tubular body. A band having an eyelet disposed therein extends across a distal end of the tissue sampling apparatus, wherein the eyelet is advantageously movable relative to the distal cutting edge in order to sever a distal end of the tissue sample.
